I've noticed a few things with the latest version...
1) No message when the "last" knight is eliminated in duel-to-the-death type games... This isn't so much of a problem when that's the only way of winning, but when it's a game with wands of securing and other objectives, there would be no way to see which way the game was won.
2) No more message about needing gems when trying to destroy book without enough gems. This used to work, so is it a result of the recent pentagram/axe change?
3) While testing today, Knights crashed for me twice when joining a third player into a duel-to-the-death game that was sitting on the "winner" screen. I tried testing with other game types, no crash, then went back to duel and it wouldn't crash after that. So no idea what's going on there.

4) "Fixed bug where you could sometimes walk through a flying axe or bolt if you were moving straight towards it." I think I saw this happen once.
5) It just crashed again while in the middle of the game. I seem to remember someone a few days ago saying it had crashed for them during a game too.
